😂 The irony of this setup is not lost on me.

I’m currently using a Windows laptop that’s running Ubuntu Linux via WSL2 to remote in to a Mac Mini to run LLMs.

Transferred my Bluesky handle to a custom domain today. Could not have been easier.

Cool article and matches similar thoughts that I’ve had for a long time on WebAssembly.

NB: It’s quite disingenuous though to compare it to Linkerd v1 (based on Finagle) when v2 (based on Rust) has existed for many years.

This morning, my wife and I watched @martin.kleppmann.com ‘s “O’Reilly Book Club” session from 2023.

In it, he notes how much research he did to avoid writing vague statements in his book. It showed.

So, I’m curious what other books out there do people feel were approached with this same rigor?

I didn’t listen to a lot of music via apps this year, but when I did it generally skewed towards post-punk/punk over the more predictable hardcore.

Inspired by @olix0r.net and @jakedonham.bsky.social’s photos to come check out this morning’s sky.
